The present invention relates to improvements intable construction andhas particular reference to tables embodying extensible top sections.

Heretofore, tables of various characters have been knownembodying-extensible tops supported on a sliding mechanism to permitextension of the top. However, to properly manufacture a'table ofthisconstruction and W to ensure easy operation thereof, the slides.

had to be made very carefully and adjustment thereof was. an operationof a delicate character which only a skilled workman could do. e

. Since the said slides were made of wood, it is easily conceived thatclimatic conditions affected the same to a great extent and that smoothoperation of the table, together with utmost rigidity could not beguaranteed to a prospective customer, under all circumstances.

Therefore, it is thema-in object of the invention to provide a slidestructure for ex- .tensible tables which is especially designed 5 toaffordconvenient' and durable operation and which is unaffected byclimatic changes.

A further object of the invention is the provision of a top supportingslide for extensible'tables constructed of metal so as to operate easilyand without substantial noise.

Another object of the invention is the provision of a table havingextensible top sections which are supported by an improved slightstructure constructed of metal and adapted to be easily assembled byrelatively unskilled labor and manufactured at negligible cost.

Other objects and advantages of the invention will become apparent asthe description progresses.

In the accompanying drawings forming a part of this specification and inwhich like reference characters are employed to designate correspondingparts throughoutthe same Figure 1 is a perspective view of a table in acontracted position,

Figure 2 is a similar view showing the top sections extended,

Figure a is a transverse sectionalview taken slide on the line 4-.4 ofFigure 3,

Figure -5 is a perspective view of the construction and assembly, and pFigure 6 is an enlarged sectional View taken on the line 66 of Figure 3.p p

Referring to the drawings, wherein for the purpose of illustrations isshown a preferred embodiment ofthe invention, the numeral 10 generallydesignates the table inits entirety embodying vertical side and endpanels, 11 and 12 forming the table frame and having fixed on the upperedges of the side panels 11 relatively narrow side bars 13. At thecentre of the table frame is mounted a relatively narrow transverse top.strip 14 rigidly attached to the side panels 11.

Slidably mounted on the frame, atopposed sides of the centre strip 14,arehorizontally slidable top sections, each of which includes a rigidportion 15 and a fiexibleportion 16 attached to the inner edge of therigid portion. As shown to advantage in Figure 6, the slidable sectionsare supported so that their upper surfaces will assume elevatedpositions with respect to the top surfacesof the side bars 13. Thisconstruction will obviate to a great extent the accumulation ofmatterinv the slit between the side edges of the slide sections and thesidebars and will enhance the appearance of the table topwhich,heretofore, has been of flush construction giving the slits at the sidesan objectionable appearance. a

a An essential feature of the invention is the provision of a supportingslide structurefor the slidable top sections; This slide structureembodies a slide mechanism designed to be mounted at the sides of thetable frame to support eachiside oftheextensible top sections. Eachslide mechanism embodies a pair of complementary exterior bars 17 and 18formed channel shaped in cross section;

end. The slot 19 is arranged in registration with a groove 21 formed inthe side panel'll, as shown to advantage in Figure 6. At the innerextremity ofeach bar 17, a roller 22 is mounted for vertical rotarymovement by 'means of a screw 22, to form a guide for the i flexibleportion 16 of each top section. The

complementary channel shaped bar 18, of each slide assembly, is attachedto the outer face of a rail 23 secured to the lower surface of the rigidtop portions 'adjacent"their sideedges and is likewise provided w1th alongitudinally extending slot 2 1 disposed 1n registration with a groove-25 formed in the i As clearly illustrated in V vFigures 5 and6, thefl'a'ngesoft he channel carries a laterally and outwardly extending1screw27. The head of the screw is initially inserted through theenlarged opening 20 formed at the-inner-endof the'slot 19, while theshank'subsequently moved-in the'remaining major portion of the slot,thehead there- 'ofpperating in the groove 21 of the table panel." ledjacent the opp'os ed orrouter end, each bar. 26 carries an inwardlyprojecting "transverse pin 28 adapted to-extend through the slot 24jandinto the groo've'25; V 1 Thus, when the adjustable' t'able top sec-'-tions'are in retracted arrangement, the side jba rs and 18. andtheintermediateslide bar -26:are disposedin substantiallyparallelposition's,the flangesof the side bars-projecting over the topand bottom edges of jthe inter- ?mediate-bar, as shown "in Figure-6. When skilled labor and in a series of succeeding operations notnecessarily done at the same time a or by the same assembler.
